Charges on bill which I did not sign up for

[LAJax]

Hello 

I'm 2 months in to a new Sky Q TV, and broadband subscription..

 I agreed a monthly cost for 18month contract but they have been adding all sorts of extras on without my consent and now the bill has doubled in the 3rd month. I cannot afford for this to be taken out in January. 
Sky Cinema being one, and another add on. 
I phone sky twice and they're trying to imply I am cancelling a contract/subscription prematurely. However I NEVER agreed to the extras and it was quite clear what my expectated monthly cost would be.

what should I do? I feel they are stealing my money as they're taking it without my agreement and without telling me.

You haven't said how you signed up to the contract in the first place so if it was by phone I would register a complaint giving them as much detail as possible about when you called so they can listen what was said to you:

If it was online do you have any emails that show what you signed up to ?

It was via the phone so I'll ask them to listen back to our conversation
